چکیده

We have previously reported on the inhibitory effect of Glycyrrhizae radix (Gl radix) on mouse endometrial carcinogenesis. The present study was performed to clarify the effects of Gl radix and glycyrrhizin (GL), the main part of Gl radix, on estradiol (E2)-related endometrial carcinogenesis. Both Gl radix and GL exerted a significant decrease in the COX-2, IL-1alpha and TNF-alpha mRNA expressions. GL generated a significant decrease in the incidence of endometrial adenocarcinoma. Accordingly, the preventive effects of Gl radix may be attributable to GL, thus being related with the suppression of COX-2, IL-1alpha and TNF-alpha. Gl radix and GL could therefore be a promising formula for the chemoprevention of human endometrial cancer.

Preventive effect of Juzen-taiho-to on endometrial carcinogenesis in mice is based on Shimotsu-to constituent.

Juzen-taiho-to, a Kampo formula, originally consists of a mixture of Shimotsu-to and Shikunshi-to formulas together with two other crude ingredients. Juzen-taiho-to is reported to have a preventive effect on endometrial carcinogenesis in mice. Shimotsu-to exerts an inhibitory effect on estrogen-induced expression of c-fos, interleukin (IL)-1alpha and tumor necrosis factor (TNF)-alpha in uteri o...

The Correlation between the Endometrial Integrins and Osteopontin Expression with Pinopodes Development in Ovariectomized Mice in Response to Exogenous Steroids Hormones

Background: The ovariectomized animals are good models to evaluate the effect of different steroid hormone treatments on implantation events and the pattern of integrin expression. Therefore, this study was performed to compare the expression of integrins and osteopontin (OPN) in correlation with pinopode development in ovariectomized mice endometrium which was subjected to steroid hormones. Me...

Cytochrome P450 1B1 gene polymorphisms and postmenopausal endometrial cancer risk.

Estrogen unopposed by progestins is a key factor in endometrial cancer etiology. Cytochrome P450 1B1 (CYP1B1), responsible for the 4-hydroxylation of estrogen, may be important in endometrial carcinogenesis, either as a regulator of estrogen availability or as a producer of potentially genotoxic estrogen metabolites. We investigated the association of CYP1B1 genotype and endometrial cancer risk...

Dietary indole-3-carbinol promotes endometrial adenocarcinoma development in rats initiated with N-ethyl-N0-nitro-N-nitrosoguanidine, with induction of cytochrome P450s in the liver and consequent modulation of estrogen metabolism

Indole-3-carbinol (I3C), found in cruciferous vegetables, has been shown to suppress or promote carcinogenesis depending on various animal models. Regarding its preventive effects, I3C acts as an anti-estrogen and can induce apoptosis, but precise mechanisms remain to be determined. Since I3C induces cytochrome P450 enzymes in the liver, it affects hydroxylation of estrogens and might therefore...
